Lab 6 Review

Question 1

How are plant pigments involved in photosynthesis?

Answer 1

They absorb sunlight

Question 2

Why is it beneficial to have several different plant pigments involved in photosynthesis?

Answer 2

To capture more parts of the spectrum

Question 3

On what basis does chromatography separate substances?

Answer 3

Based on their solubility

Question 4

What experimental conditions were used in this laboratory to test for cellular respiration in photosynthesizing plant cells?

Answer 4

Carbon vs non-carbon

Question 5

Photosynthesis: Organelle? Gas given off? Gas taken up?

Answer 5

Chloroplast, O2, CO2

Question 6

Cellular Respiration: Organelle? Gas given off? Gas taken up?

Answer 6

Mitochondria, CO2, O2

Question 7

Answer 7

The use of solar energy to produce a carb

Question 8

Answer 8

Separates the pigments located in leaves

Question 9

White light

Answer 9

Contains all colors of light

Question 10

The Calvin cycle

Answer 10

Plant takes up CO2 and reduces it to carbs

Question 11

Where do light reactions take place

Answer 11

Happens in the thylakoids

Question 12

Rf formula? Higher Rf value?

Answer 12

Rf=d.pigment/d.solvent

Higher Rf value=more soluble

Question 13

Formula for Photosynthesis

Answer 13

CO2 + H2O —(sunlight)—> C6H12O6 + O2
